The 10 Most Popular Hairstyles

Jennifer Aniston

Whether you call it "The Jen" or "The Rachel," there's no denying the fact that Jennifer Aniston's layered bob is "the most requested hairstyle of all time," Tricomi says. "Everyone wanted this style," Hershberger says, "it's a very pretty, 'girl next door' look." It perfectly frames your face and makes you totally approachable and "friend"-ly. Not all '90s hairstyles were that lucky.
